TPMS without metal valve stems?
I purchased the TST 507 flow through TPMS about 4-5 years ago for our travel trailer, which I had metal valve stems put on when I replaced the tires. We have since purchased a 5th wheel and apparently the way the stem opening is on the wheels they cannot use metal valve stems, just the rubber ones (they're slightly recessed). While on a 10k road trip this summer we encountered a situation where one of our tires was running a little low. It turns out that the rubber valve stem was not holding up with the TPMS on it and was leaking air around the seal. My question is....is this just something I'm going to need to deal with or are there other alternatives that will work with a rubber valve stem?
